SPECIFICATION forming part of Letters Patent No. 767,366, dated August9, 1904.

' Application filed October 25,1902.

T0 (0Z7 whom, it may concern:

Be it known that we, RICHARD M. WA'rsoN and WILLIAM T. MoGEAw, citizensof the United States, residing at Detroit, county of \Vayne, State ofMichigan, have invented a certain new and useful Improvement in Cash-Registers; and we declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same,

reference being had to the accompanyingdrawings, which form a part ofthis specification.

This invention relates to cash-registers, and has for its object acomplete throw mechanism intended to be used to compel the operator togive to the main or primary key its complete swing and to hold theprimary key until the read justing-key is actuated at the end of acomplete cycle of operations.

A further object of the invention is to lock the readjusting-key againstactuation until the primary key has made its complete throw and returnedto its normal position.

For a full understanding of the invention it is only necessary toexamine the primary key, the readjusting-key, and the parts immediatelyconnected with and in a way intermediate between the two withoutconsidering the other parts which enter into the full cycle of action inthe operation of the register.

In the drawings, Figure 1 shows an elevation of the two keys and theparts immediately connected with them. Fig. 2 shows the locking devicefor the readjusting-key. Fig.

3 shows detached the parts that coact with the pawl 6. I

A indicates the framework which supports the rod B, on which the mainkeys 1 are journaled. It also supports a rock-bar C, that is actuated bythe readjusting-key 2. The readjustingkey 2 is a reach-rod extendingfrom bar 3 to the outside of the case through a suitable opening in thecase. The bar 3 is a tiebar between two rock-arms, one of which, 4, isshown in the drawings and the other of which is not seen. To the innerend of the main key 1 is attached or secured a short rack 5, that hangssubstantially vertical from the Serial No. 128,722. (No model.)

end, and the lower end of the rack is radially further from the pivot orbar B than the upper end. I A pawl 6, common to all the keys, ispivotally secured to a pivot 7, supported by hangers from some fixedpart of the case, and connected with or attached to the pawl is a hook8, arranged to engage at times over the edge of the square bar 9, thatserves as a detent. the pawl and engages by gravity behind the corner ofthe bar 9. hen the free end of the pawl 6' is lifted and the hook 8pushed backward suificiently to engage behind the rod 9, the pawl isheld out of engagement with the rack and the key can swing, but willproduce no actuating result on either indieating or registeringmechanism. The rockarm 0 from shaft C engages the stem of the hook 8 andlifts the hook oil from its engagement with the bar 9 when thereadjustingkey is pushed inward and the rock-bar C oscillated thereby.Contemporaneously with this movement a pawl 11, which has served to holdup the indicator-rod 12, is oscillated from engagement, theindicator-rod 12 drops, and the primary key is now in condition to againperformits proper part in a new cycle of action.

The readjusting-key is locked against actuation at times when during thecycle of operations it should be locked by a hook 14, that is pivotallysupported on the frame-bar 15 and engages over the bar 3, that formspart of the rock-frame on the lock-bar C. The opposite bar 3 at the endof the rock-arm 4 is coupled by link 4. to a swinging strut 16, whoseoflice is to engage under the locking-bar 17, on which the free end ofthe primary actuating keys rest. The bar 17 rests on a strut 21, thatrises from a swinging lever 22, and the lever 22 1s coupled by a link 23to the arm 20 of a pawl-like lever that at times engages in front oftooth 19 on link 18. The forward end of link 18 is supported on swingingstrut 18, and the rear end of the link is provided with an elongatedoval slot 18, through which the rock-rod 3 engages. The link 18 actuatesthe indicator-shield through mechanism part of which is shown, but whichneed not be referred to further, as it forms no part of this invention.

The pawl-like lever 20 20 is under tension of a spring 20 at all times.The end 20 of lever 20 engages the tail of the hook let and lifts thehook when the end 20 drops or allows the hook to drop when the end 20 islifted.

The cycle of operations beginning with the readjusting push or inwardthrust of the key 2 is as follows: The key 2 is pushed upward, pushingback the rock-bar 3, which draws back with it the link 18 until the linkas- .sumes the position shown in the drawings. WVhen in this position,the pawl 20 engages in front of the tooth 19 and prevents the link fromreturning to its forward position. hen the key 2 was in its in positionand the bar 3 drawn backward, the strut 16 was swung un-- der thehanger-bar 17 and the free end of the .primary key could not bedepressed; but immediately upon releasing the key 2 the bar 3 swingsforward and the strut l6 swings back from under bar 17. The outer end of23, swings lever 2O 20 from in front of tooth 19, and link 18 beingreleased from the backward pressure of the lever 20 against the tooth l9and being connected to the then actuated swing-strut l8 swings forward;but so long as-the key is held down and the end 20 of lever 20 20remains lifted and the hook 14 remains in engagement with bar 3 the key2 cannot make a backward thrust, as soon, however, as key 1 is releasedthe lever 20 drops, engaging against the short arm of the lever whoselong arm carries the hook 14, lifts hook 14, and the cycle of operationis complete.

What we claim is In combination with the primary key, a pawl, a rackactuated by said primary key, engaging with said pawl and arranged toproduce a consecutively step-by-step movement in the throw thereof, ahook arranged to detain the pawl after reaching its greatest throw, areadjusting-key and intermediate parts actuated thereby, arranged torelease the hook, substantially as described.

In testimony whereof we sign this specification in the presence of twowitnesses.
